DETAILED DESCRIPTION

For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the disclosure as oriented in FIG. 1. However, it is to be understood that the disclosure may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary aspects of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the aspects disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

Referring to FIGS. 1-17, a seating assembly 2 includes a seating surface 4 that extends over at least one of a seat 6 and a seatback 8. The seating assembly 2 also includes a fluid mover 10 and a fluid transfer member 12. The fluid transfer member 12 comprises a fluid inlet portion 14 and a fluid outlet portion 16. The fluid inlet portion 14 is coupled to the fluid mover 10, and the fluid outlet portion 16 is proximate the seating surface 4. The fluid mover 10 is selectively operable to direct pressurized fluid through the fluid transfer member 12 to deliver a cooling effect at the fluid outlet portion 16 to cool the seating assembly 2 occupant.

Referring to FIG. 1, the seating assembly 2 is illustrated inside a cabin 17 of a vehicle 15. The seating assembly 2 may be a seat for a driver, a seat for a passenger, a rear bucket seat, a rear row of seats or any other vehicle seat. The seating assembly 2 includes a seat 6 and a seatback 8 pivotably attached to the seat 6. The seatback 8 of the seating assembly 2 includes a forward facing portion 18 and a rearward facing portion 20. In various aspects, a trim cover 22 covers the forward facing portion 18. The seat 6 of the seating assembly 2 includes an upward facing portion 24 and a downward facing portion 26. In various aspects, a trim cover 22 covers the upward facing portion 24. The seating assembly 2 also includes a headrest 28 operably coupled to an upper portion 30 of the seatback 8. The seating assembly 2 also typically includes a seat base 32 configured to provide structural support to the seating assembly 2. The seat base 32 is preferably supported on seat mounting rail assemblies 34. The seat mounting rail assemblies 34 are configured to allow the seating assembly 2 to be adjusted in forward and rearward directions relative to the longitudinal axis of the vehicle 15. The seating assembly 2 is slidably coupled with a floor 36. It is also conceivable that the seating assembly 2 may not include the seat mounting rail assemblies 34 and alternatively may be fixedly coupled with the floor 36 of the vehicle 15.

In certain conditions, when temperature and atmospheric conditions are outside of an occupant's comfort range, the seat 6 and the seatback 8 may be uncomfortably warm such that the seating assembly 2 may not provide the occupant with comfortable transit in a vehicle. Accordingly, a cooling effect is achieved at cooling zones 40 as generally set forth in FIGS. 1-17 with the release of pressurized air jets 41 that cool the occupant's skin and penetrate the occupant's clothing, thus providing for a more pleasant traveling experience for the occupant.

Referring to FIG. 2, the fluid transfer member 12 may include a first portion 42 and a second portion 44. The seating surface 4 includes a seat surface 46 and a seatback surface 48. In the depicted aspect, the fluid transfer member first portion 42 is proximate the seat surface 46. The fluid transfer member second portion 44 is proximate the seatback surface 48. The fluid transfer member first portion 42 and the fluid transfer member second portion 44 are in communication with the fluid mover 10. The fluid mover 10 pushes pressurized fluid through a fluid passageway 50 and into the fluid inlet portion 14 of the fluid transfer member 12. Arrows 51 show fluid flow from the fluid mover 10 through the fluid passageway 50. Arrows 52 and 54 show fluid flow in the fluid transfer member first portion 42 and the fluid transfer member second portion 44, respectively. The pressurized fluid leaves the fluid transfer member first portion 42 and the fluid transfer member second portion 44 at the fluid outlet portions 16.

With reference again to FIGS. 2 and 5, in various aspects, the fluid transfer member 12 may include one or more tubes 60. In the depicted aspect, the fluid transfer member first portion 42 and the fluid transfer member second portion 44 include one or more tubes 60. In various aspects of the present disclosure, the tubes 60 typically have a first aperture 62 and a second aperture 64. In various aspects of the disclosure, the first aperture 62 is typically an inlet aperture that is in communication with the fluid mover 10. Referring to FIG. 3, in various aspects of the present disclosure, the second aperture 64 is typically an outlet aperture 70 that has a release point 72 of the pressurized fluid that exits the tubes 60 to cool the seating assembly 2 occupant. Referring to FIGS. 6 and 15-17, in various aspects of the disclosure, a tube 60 (or gallery 98 or conduit 160) may include additional outlet apertures 70 (or gallery outlet portions 102 or conduit outlets 178) including at least a third aperture 66, and/or a fourth aperture 68. Referring to FIGS. 2-3, the outlet aperture 70 is typically a metered vent. In various aspects, the metered vent may have a diameter of approximately 0.2 mm to approximately 0.6 mm. To achieve greater or lesser fluid pressure through the metered vent, the fluid mover 10 works more or less. The outlet apertures 70 are arranged in cooling zones 40 suitable for an occupant's cooling physiology. Referring to FIGS. 13-14 and 16-17, in various aspects, a perforated trim cover 22 is between the occupant and the fluid transfer member 12. In various aspects, a permeable topper pad 173 is between the trim cover 22 and the fluid transfer member 12.

Referring to FIGS. 1-17, in various aspects, an adiabatic process utilizing a fluid mover 10 that is a compressor and the fluid transfer member 12 achieves pressurized air at outlet apertures 70 that typically penetrates the permeable topper pad 173, the perforated trim cover 22, and an occupant's clothing to cool the occupant's skin. In thermodynamics, the adiabatic process for ideal gases stands for no transfer of heat or matter out of a system (Q=0). The adiabatic process for an ideal gas is isothermal. However, for air at ambient temperatures, adiabatic compression of a gas causes a rise in the temperature of the gas. Adiabatic expansion against pressure, for example a spring or a metered vent, causes a drop in temperature. In various aspects of the disclosure, the fluid is air or a gas that behaves like air in typical vehicle conditions at ambient temperature. The pressure drop at the point of ambient air release (the release point 72) typically causes an adiabatic temperature reduction.

In various aspects of the disclosure, the fluid mover 10 is a compressor that provides pressurized ambient air to the fluid transfer member 12. The compressor may provide pressurized ambient air with pressure that is approximately 150 times higher than the pressurized ambient air that a typical vehicle seating assembly air mover provides. For example, according to various aspects, a typical pressure of a vehicle seat fan may be approximately 0.066 psi. In various aspects, the pressure that a typical compressor generates may be approximately 10.0 psi, which is approximately 150 times higher than 0.066 psi. The increased air pressure of the compressor has numerous advantages over the air pressure generated by a typical vehicle seating assembly air mover. The increased air pressure of the compressor allows a thinner and more flexible fluid transfer member 12 to be used in the seating assembly 2. The increased air pressure of the compressor provides usable residual air pressure at the outlet aperture 70 to purge warm moist air from the clothing of the occupant. The pressure drop at the outlet apertures 70 of the fluid transfer member 12 provides a lower temperature that cools the occupant while providing enough pressure to penetrate the occupant's clothing.

Referring to FIG. 4, in various aspects a radiator 80 or other heat dissipation member (cooler) may be used to dissipate heat from the compressed fluid that may enter the compressed fluid due to work from the fluid mover 10. The fluid mover 10 is coupled to fluid passageway 50. In the depicted aspect, a plurality of fins 82 emanates from the radiator 80. In the depicted aspect, air depicted by arrow 84 leaves the fluid mover 10 and enters the radiator 80. The radiator 80 absorbs heat from the air traveling through the radiator 80. Heat leaves the radiator 80 in the direction of arrows 86. Air exits the radiator 80 at arrow 88. Typically, the air that exits the radiator 80 at arrow 88 has a lower temperature than the air that enters the radiator 80 at arrow 84. The radiator 80 typically increases the efficiency of the adiabatic process by removing heat from the air before it enters the fluid transfer member 12.

The Joule-Thompson Effect may also be used to achieve cooling at the release points 72 of the pressurized air. In thermodynamics, the Joule-Thompson Effect describes the temperature change of a real gas or liquid (as differentiated from an idea gas) when it is forced through a valve or porous plug while it is kept insulated so that no heat is exchanged with the environment. At room temperature, air cools upon expansion by the Joule-Thompson Effect. The Joule-Thompson Effect may be observed during the throttling process. With reference to FIG. 4, a radiator 80 typically increases the efficiency of the Joule-Thompson Effect by removing heat from the air before it enters the fluid transfer member 12.

By way of example, in various aspects, an air supply of approximately 25 psig is contained in a fluid transfer member 12. The air supply releases air beneath the occupant. The seating surface 4 will experience a temperature drop. The temperature drop occurs directly and at the pressure release point 72 as the pressurized air is at ambient temperature. Typically, minimal insulation is required, and typically there is little loss of cooling capacity.

In various aspects, the temperature of the pressurized air leaving outlet apertures 70 may be as low as approximately 5.0 degrees C. (41 degrees F.). In various aspects, the seating surface 4 may experience a temperature drop of approximately 15.5 degrees C. (60 degrees F.) to approximately 5.0 degrees C. (41 degrees F.).

With regard to FIG. 5, a schematic representation of the general layout of the tubes 60 of the fluid transfer member 12 is shown. The fluid transfer member first portion 42 and the fluid transfer member second portion 44 are in communication with the fluid mover 10. A fluid passageway 50 delivers fluid from the fluid mover 10 to the fluid transfer member 12 inlet portion 14. Tube outlets 70 are located at the ends of the tubes 60. The tube 60 lengths (L₁, L_(1A), L_(1B), L₂, L_(2A), L_(2B), L_(2E), L_(2D), L_(2E), etc.) generally represent approximate distances from the tube 60 first (inlet) aperture 62 to the tube outlet aperture 70 (second aperture 64) to arrange release of cool air according to an occupant's physiology at targeted cooling zones 40. In various aspects, numerous tubes 60 are present in a fluid transfer member 12. In various aspects, scores of tubes 60 are present in a fluid transfer member 12. In various aspects, more than a hundred tubes 60 are present in a fluid transfer member 12.

Referring to FIG. 6, in various aspects, the fluid transfer member 12 may be a trim cover panel 96 having extruded fluid galleries 98. A portion of a trim cover panel 96 with extruded fluid galleries 98 is depicted in FIG. 6. The fluid galleries 98 have inlet portions 100 that are in communication with a fluid mover 10. The fluid galleries 98 have outlet portions 102 that are located proximate the seating surface 4. In the depicted aspect, the outlet portions 102 are metered holes. In various aspects, the fluid mover 10 is a compressor and the fluid is air. In various aspects, pressurized air is routed from the compressor, through the fluid galleries 98 of the trim cover panel 96, and out of the fluid outlet portions 102. In the depicted aspect, each fluid gallery 98 may have a gallery entry at inlet portion 100 and one or more gallery exits at outlet portions 102. In various aspects, the outlet portions 102 are fine diameter exit jets 104 with a high pressure drop upon exit of pressurized air from the outlet portions 102. In the depicted aspect, the top edge 106 of trim cover panel 96 is sealed. In the depicted aspect, a cover stock 108 is bonded to the panel's A-surface 110. In various aspects, the trim cover panel 96 is an extruded soft and flexible air distribution panel. The pressurized air exit jets 104 cool an occupant.

The fluid transfer member second portion 44 is proximate the seatback surface 48. The occupant 112 sits in the seating assembly 2. Pressurized air at arrows 114 cools the occupant's back, buttocks, and legs at various cooling zones 40. The pressurized air at arrows 114 typically moves from the release point 72 directly through the trim cover 22, which may be perforated or porous in various aspects, and typically cools the occupant 112 by dropping the temperature of the air at arrows 114 while typically retaining residual pressure to infiltrate the clothing of an occupant until the skin of an occupant is reached. In various aspects, a chilled air supply at arrows 114 is typically brought directly into contact with the occupant's skin to cool the clothed occupant 112 quickly and strongly. In various aspects, adiabatic cooling for ambient air or the Joule Thomson Process for ambient air, is used to chill the fluid at arrows 114 released immediately beneath the trim cover 22 enabling its residual pressure to infiltrate clothing.

In various aspects, the first fluid passageway 134 may be a plenum. With reference to the seat 6, channels 140 emanate from the first fluid passageway 134. Channel inlets 142 are coupled to the first fluid passageway 134. Channel outlets 144 are proximate to the seat surface 46. With reference to the seatback 8, a second fluid passageway 136 emanates from the fluid mover 10.

The topper pad 173 overlays the carrier 172 and the cap 152 and is proximate the trim cover 22. The trim cover 22 is generally or locally perforated. The conduit 160 is coupled to the holder 150 and provides air flow into the holder 150 at arrows 174. The pressurized air at arrow 176 is released from the conduit outlet 178 into the holder 150. In various aspects, the conduit outlet 178 includes a pressure maintaining exit flow restriction 180 which may be a metered vent.

A variety of advantages may be derived from the use of the present disclosure. A direct, through seat cover air cooling of the occupant is achieved by dropping the temperature of an air supply while retaining some residual pressure to infiltrate the occupant's clothing. An occupant may be cooled quickly or strongly with a chilled air supply that is brought directly into contact with the occupant. An air supply is released immediately beneath the seat trim cover so that it is close to the occupant and thus able to have the air supply's residual pressure infiltrate the occupant's clothing. The fluid transfer member may be designed to cool various occupant cooling zones. For example, more economical applications may require fewer cooling zones while more expensive applications require more cooling zones. Cooling zone selection may also be based on an occupant's size, anticipated vehicle use, vehicle climate, and other factors. The size and location of the fluid transfer member may be selected based on vehicle needs.
